DRAINAGE SYSTEM.- 7

Specification of Letters Patent.

To all whom it may concern:

Be it known that ,1, CHARLES 1V. Osnonnn,

' a citizen of the United States, residing at devices for draining low,wet lands or lake basins such as are found in Texas.

The object of the invention is to provide a drain tube or cribbing-ofpeculiar constructron which may exten from the surface to a 5 lowerstrata of gravel and sand and which has at its top means for preventingit from being filled with leaves, twigs,'and other trash.

-With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully descri ed and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a vertical section throughmy improved drain device; and Figifl is a top plan view.

In the drawings 1 denotes a vertical passage or well wh ch may bedrilled or dug from the surface 2 of the lake basin to a lower strata 3of sand gravel, or the like, through which the water draining" from thesurfac'e2 will passJYlhe passage 1 is lined with a tube or cribbing 1 ofany suitable .form and construction but preferably made of longitudinalsections of unequal length so tric strainers 6, 7 8 made? fromo'iiierent sized mesh woven wire and secured to an an- *nu-lar' seriesof upright posts 9. as shown more clearly in Fig... 1.. The outermoststrainer or screen 8 is made preferably, from comparatively coarse wirenetting, the inter- Patented July 5, 1910.

Application filed September 11, 1909. Serial No. 517,194.

mediate one 7 is made of somewhat finer mesh material while the innerone 6 is of still finer mesh material. These several strainers orscreens extend from the surface upwardly to a. point above high watermark in the lake basin or lowland where the drain device is located. Itwill be understood that one or more of the drain devices maybe providedin each lake basin and that they may be of any size.

In order to permit the upper end of the well or passage 1 to be closedso that/water may be allowed to remain in the basin long enough totlioroughly saturate the soil, I provide a removable top or cover 10 forthe flat upper end of said well. lhis cover which is )referably hingedas shown at 11 is adapte to be, raised or lowered by means of anoperating wire cord 12 or the like. The latter is attached to the cover10 and passed over a guide pulley 13 on one of the' posts, and also overone or more similar guides 14, and may have a hand piece 15 atits otherend. This removable cover or lld for thewell is exceedingly advantageousin the lake basins above referred to because in winter and early springsuch basins are usually dry, and should there be little rain the watermay be allowed to accumulate until the crop has been suliicientlywatered and by raising the lids of the well water' tel-mediate ones,supportingaangs'foi-.said
